What does it mean if an element has 8 valence electrons?
The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds.
How many valence electrons does s 32 have?
6 valence electrons
Can you have 9 valence electrons?
Some molecules can accommodate more than 8 valence electrons because they have expanded valence shells. These molecules are from periods 3 or higher because starting from n=3, atoms have d-orbitals that can accommodate for more that 9 valence electrons.
Why does sulfur only have 6 valence electrons?
Sulfur has one more electron pair in its 3s subshell so it can undergo excitation one more time and place the electron in another empty 3d orbital. Now sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell.
How many valence electrons should a neutral at atom have?
For neutral atoms, the number of valence electrons is equal to the atom’s main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
How many valence electrons does a neutral atom of phosphorus have?
5 valence electrons
How many valence electrons does each oxygen atom need to be stable?
eight valence electrons
How many valence electrons does each nitrogen atom have now?
How many oxygen atoms are stable?
How many electrons does the oxygen atom need to become stable quizlet?
Oxygen has six valence electrons, and that means it needs to gain two to become stable, but it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2.
How many valence electrons does oxygen share with each hydrogen atom?
A: The oxygen atom shares one pair of valence electrons with each hydrogen atom. Each pair of shared electrons represents one covalent bond, so two covalent bonds hold the water molecule together.
When an atom of oxygen has 8 valence electrons Why is it more stable?
Each oxygen atom shares 2 of its six valence electrons with the other. The diagram shows that each oxygen atom is then in contact with 8 electrons. Each has then achieved its “octet” in the molecule, so the molecule is more stable than the individual oxygen atoms.
How many valence electrons are in a single hydrogen atom and a single oxygen atom?
1. Determine the total number of valence electrons in the molecule or ion. Each hydrogen atom (group 1) has one valence electron, carbon (group 14) has 4 valence electrons, and oxygen (group 16) has 6 valence electrons, for a total of [(2)(1) + 4 + 6] = 12 valence electrons.
How many valence electrons are in a single hydrogen atom?
one valence electron
Are oxygen atoms stable?
The oxygen atom forms a covalent bond with another atom of oxygen and shares 2 electrons in order to make the valence shell electrons to be equal to 8. An oxygen molecule(O2) with two atoms of oxygen is stable.
How many atoms of hydrogen would a single nitrogen atom bond to?
How many hydrogen atoms will bond to the oxygen atom?
Two hydrogen atoms
Why can nitrogen have 4 bonds?
If you look at the above image you can see that when nitrogen has a positive charge (one less electron), it can form four covalent bonds. Either with single, double, or triple bonds. It is similar to phosphorus in this regard because they both have five valence electrons (four when they have a positive charge).
Are hydrogen bonds weak?
Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.
